Very funny stuff here. The CLC-1, 200 and 500 were unable to detect cashola on the copy glass. With the intrduction of the 300 and up (550, 700 and upto the 1000) the anti-counterfieting logic was built in. It is not able to actually recognize the image of money. It recognizes the color of green. So yes certain images will not reproduce. One of my old customers would copy about 15k worth of golf course pics from around the country. There were about 1% that would print with the green mask over the image. That is if the lamp was new and the scanner had a recent ccd adjust. As it aged the error would become more frequent. None of the machines ever recorded the error or the scan in any way. Even if they did you could always just clear the ram on the DC controller! The counters on all these machines are mechanical. The serial number on all these machines has been recorded on each copy since the introduction of the 550. It is done in yellow and is not in the image. ;-> With a lupe you can even see it.
